Masking tape is a type of pressure sensitive tape mae with an easy-to-tear thin paper, and fly back and a removable pressure sensitive adhesive. It is used mainly in painting, to mask off areas that should not be painted. The adhesive is the key element to its usefulness, as it allows the tape to be easily removed without leaving residue or damaging the surface to which it is applied. The tape is available in several strengths, rated on a 1–100 scale based on the strength of the adhesive. Most painting operations will require a tape in the 50 range. Household masking tape is made of an even weaker paper and lower grade adhesive. There is also a song called 'Round and Round the masking tape,' produced by Adam Davies.
